JOHN ALDEN LEE, OF OELWEIN, IOWA.

BOOK-MARKER CLIP.

Specification of Letters Patent.

Patented Feb. so, 1917..

Application filed April 2, 1915. Serial No. 18,638.

To all whom it may concern:

Be it known that 1, JOHN ALDEN LEE, a citizen of the United States, anda resident of the town of Oelwein, in the county of Fayette and State ofIowa, have invented certain new and useful Improvements in Book-MarkerClips; and I do hereby declare that the following is a full, clear andexact description of the same, reference being had to the accompanyingdrawings, and to the numerals of reference marked thereon, which form apart of this specification.

This invention relates to a book marking device adapted to be attachedto or detached from the page of a book without in any way interferingwith the opening or closing thereof, and has for its object to providecertain improvements in the construction of the same as will hereinafterbe more definitely pointed out and claimed, reference being had to theaccompanying drawing, in which Figure 1 is a plan view of a book in openposition with book marker devices embodying the principles of myinvention attached to certain pages thereof.

Fig. 2 is an enlarged plan View of one of the marking devices.

Fig. 3 is a sectional view thereof shown attached to a page.

As shown in the drawings:

The covers of a book are denoted respectively by the reference numerals1 and 2, with pages 3, bound therebetween. My invention for attachmentto one or more pages is illustrated in detail in Figs. 2 and 3, and anumber of the devices so constructed are shown attached to differentpages of the book illustrated in Fig. 1.

The device consists of a unitary strip of resilient metal bent to formdouble ply jaws 4 and 5, respectively, of which the member 5, of thejaws is slightly longer than the member 4, as clearly shown in Figs. 2and 3. The ends of the metal strip afford actuating finger pieces 6 and7, respectively which, when pinched together, serve to open the jaws 4and 5. If desired, as clearly shown upon the devices illustrated inFigs. 1 and 2, an indicating character ,or numeral may be enameled onthe upper surface of the finger piece 6, or attached thereto in anysuitable manner, if so desired. It is to be understood that theillustration of the device in Figs. 2 and 8,- is considerably enlarged.This is obvious when it is remembered that the thickness of a page of abook is very small, so that the required movement for separation of thejaws 4 and 5, to grip the margin of a page is, to all intents andpurposes, practically negligible.

The elongated jaw 5, greatly facilitates attachment of the clip to apage, as said jaw may be projected beneath a page and the jaws thenopened to engage the page therebetween. However, the possible opening ofthe jaws 4 and 5, is sufficient to permit more than one page to begripped therebetween if so desired, although ordinarily this isunnecessary.

The clip is also formed with reinforcing ribs 8,which afford recessesfor reception of the tips of the fingers, thus facilitating manipulationof the clips. Then, too, an indicating character such as the numeral 5,printed on paper or celluloid, may be placed fiat within the recessedportion of the clip on the portion 6, thereof.

am aware that various details of construction may be varied through awide range without departing from the principles of this invention, andI therefore do not purpose limiting the patent granted otherwise thannecessitated by the prior art.

I claim as my invention:

A book marker clip, comprising a single piece of spring material bent atsubstantially its center to form substantially a semicircular portion,the ends of said material being again folded upon themselves to formclamping jaws, one of said jaws being longer than the other, thematerial at the ends of said jaws being extended upon the opposite sideof the semi-circular portion, said opposite ends forming finger piecesfor manipulating said clamping jaws and being provided with reinforcingribs which afford recesses to receive indicating characters therein.

In testimony whereof Ihave hereunto subscribed my name in the presenceof two subscribing witnesses.
